SAFETY INSTRUCTIONS - IMPORTANT NOTES
Road Traffi c Licensing Regulations (StVZO)
The applicable regulations of the StVZO must be observed in respect of fi xed installation of the turntable on
a vehicle which is driven on public highways.
In particular, this applies to §§ 19/2; 30 C; 32 (2) and the EC directive 74/483 EEC.
Briefl y, they state that no endorsement of the vehicle documentation is required unless the antenna unit
causes the height of the laden vehicle to exceed 2 m, or the antenna unit projects beyond the outer lateral
outline of the vehicle. The maximum permissible height of 4 m (vehicle and antenna unit) may not be
exceeded.
There is an increased risk of accidents if the normal vehicle height is increased by
an extended antenna. The driver bears sole responsibility for the condition of the
superstructure and external fi ttings!
Cables
Lay all cables such that nobody can tread on them or trip over them.
To prevent parasitic induction or interference emissions, when extending the antenna cable use 75
Ω
coaxial
cable with a screening factor of at least 75 dB.
If you tied the cables together with wire or similar materials, remove this to prevent the risk of fi re!
Power supply, fusing
Operate the system from your vehicle‘s battery (12 V) or a suitable mains power supply unit. This mains
power supply unit must ensure a stable output voltage of 12 V, continuous current of 11 A and 15 A (300 ms)
surge current.
The transient current consumption is up to a maximum of 12 A.
To ensure reliable functioning of the connection/control unit, the power supply cable must be connected
directly to the battery. If the supply voltage is too low, the UFS 740sw receiver indicates this with the on-
screen message “On-board voltage too low” on the television screen.
A 15 A fuse is incorporated in the power supply cable. If the fuse blows, rectify the source of the fault and
replace the blown fuse with a fuse of the same rated value (15 A).
Never remove or bypass the fuse in the cable – cable fi re hazard!
Connecting the power supply cable wire marked “Ignition” to the ignition circuit activates the turntable
function for automatic lowering of the antenna. This lowering takes place as soon as the vehicle ignition
circuit is turned on. When connecting the control unit to the on-board power supply, it must be ensured
that the “+12V”, “Earth” and “Ignition” wires cannot be interrupted by intermediate switches, as this could
deactivate the automatic lowering function.
The antenna is lowered within 12 seconds of the ignition being switched on (if it is in
stand-by mode and if the UFS 740sw is switched off). Otherwise the control unit that is
in use is lowered immediately.
Important:
Lowering the antenna can take up to 30 seconds after the ignition is switched on)!
